APPARATUS FOR DILG GING, TREATING, AND DELIVERING MARL.

SPECIFICATION forming part of Letters Patent No. 699,974, dated May 13, 1902. Application filed July 20, 1901. Serial No. 69,078. (No model.)

To all whom it may concern:

Be it known that we, CHARLES J. REILLY, residing at Syracuse, in the county of Kosciusco and State of Indiana, and SPENCER B. NEWBERRY, residing atSandusky, Erie county, Ohio, citizens of the United States, have invented. a certain new and useful Improvement in Apparatus for Digging and Treating Marl and Delivering it into Re- IO ceivers, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings.

Much of the marl used in the manufacture of Portland cement is found in deposits of" greater or less thickness on the bottom of lakes. This marl is dredged and carried ashore and into the factory, where after the different small batches have been chemically analyzed the other ingredients are added in proper proportions, determined by such analyses.

The object of this invention is to economically get the marl from the bottom of the lake and deliver it to the factory on shore in the best condition for determining at minimum expense 'what other ingredients and how much thereof must be mixed with said marl to' make the desired cement mixture.-

The invention consists in the construction and combination of parts, hereinafter described, and pointed out definitely inthe claims.

Referring tothe drawings, Figure 1 is. a side'elevation of the entire apparatus. Fig.

2 is a plan view thereof. Fig. 3 is an enlarged side elevation, partly in section, of a portion-of a boat and the mechanism which it carries. v broken away, of the same mechanism which 0 is shown in Fig. 3.

View of the pipe and valve system associated with the two tanks. 7 tion of a part of the same pipe and valve system. Fig. 7 is an end view thereof. Fig.

8 is a plan'view thereof, and Fig. 9 is a sectional end view thereof.

Referring to the parts by letters, A represents a. boat, preferably a flat-bottom scowlike structure. It carries, among other things,

a dredging apparatus, preferablya continuous Fig. 4 is a plan view, partly Fig; 5 is a diagrammatic Fig. 6 is a sidee1evabucket-dredge B. There is nothing new in this bucket dredgein itself, either in respect to its construction or the mechanism for operatin g it. Wherefore it is not thought necessary to describe it further than to say that its buckets b. are adapted to dig the marl from t'he bottom of the lake and to carry the same toan elevatedposition and to discharge it into a chute O, through which it falls into a pug-mill D. This pug-mill may be of any suitable constructioncapable of disintegrating the lumps of marl and of mixing the disintegrated marl with water to make a thin homogeneous mud or slurry. Connected with the discharge end of the pug-mill is a hopper E, having two branch pipes e e, which severally discharge into two stout air-tight metal tanks F F, arranged side by side in the bottom of the boat. These tanks have discharge-pipes H H, whose outer ends are connected with a flexible pipe J, which extends to the shore. The inner ends of these pipes extend into said tanks and are turned downward, and their open lower ends are in slight depressions f in the bottoms of the said tanks. By this construction substantially all of the contents of the tanks canbeQdiScharged through these pipes by the method to be explained. This flexible pipe J is made of sections j, connected by flexible joints j, and the Wholefiex'ible discharge-pipe is supported by floats K, connected thereto at suitable intervals. The shore end of this flexiblepipeis fixed and is connected'with a branched, pipe M, whose branches m have valves m and are adapted to severally discharge into'tanksN N. On

the boat is also an air-compressor G, of any suitable form. 'j.It (or 'a'compres'sed-air accumulator) is connected with the tanks F F bypipes 99, in which are valves 9 'There are also valves h h in the discharge-pipes H I andvalves e e inthe inlet-pipes e 6'. While these several valves may be of any suitable construction and may be operated by any'suitable means, we prefer to employ the construction and operating mechanism shown in the drawings, and particularly in Fig. 5. Each of the valves h h e e is a slidevalve and is connected with a piston 7, which is movable in a fixed cylinder R. Two comthere are valves to be operated, as described,

by compressed air. Each of these branch pipes q is connected with a valve-casing T, and with each of these valve-casings a branch discharge-pipe v is also connected, the several branches 1: being connected with a main discharge-pipe V, which is open to the atmosphere. An associated pair of air-pipes r r are also connected with each of these valvecasings and lead therefrom to a cylinder R,

as before specified. In each valve-casing is a Valve 25, by means of which either one of the pipes r r may be placed in communication with the pipe q, while the other is placed in communication with the pipe 4). These several valves are provided with operatingarms 15, which are all connected with a single operating device 6 and the valves are so set that compressed air is admitted into the pipes r, associated with the valves e and h, whereby said valves will be closed, and at the same time air is admitted to the pipe 0, associated with the valves 0 and h, whereby said valves will be opened. By the operation of the single operating device t the position of all of these four valves will be reversed.

The valves g are severally in valve-casings g g. The pipe 9 and a branch q of the pipe Q and a branch 1) of the pipe e are connected with the valve-casing 9 while the pipe 9 and a branch air-pipe q and a branch discharge-pipe c are connected with the easing g These valves 9 g are of such construction that when they are in one position air from the pipe q will fiow into the corresponding tank, while if they are in another position the air may flow from said tank through the pipe V and thence into the atmosphere.

In the operation of the described mechanism the various valves may be in the position shown in Fig. 5, in which case the thin slurry from the hopper E is flowing through the pipe 6' into tank F, the outlet from said tank being closed by valve 7L, and the valve 9 being in such position that air may freely escape from said tank. At the same time the tank F, having been previously filled, is receiving compressed air (the valve 9 being properly turned, as shown) the valve 6 is closed and the valve 7b in the outlet-pipe H is opened, and therefore the compressed air is forcing the slurry from the tank F through the pipe H and the flexible pipe K to the shore, where it is being received into either of the receiving-tanks desired. When this tank F is emptied and the tank F is filled, the valve g is first turned to disconnect the tank F from the air-compressor and allow the air in said tank to escape to the atmosphere. Then the valves tare operated, the result being that the position of several valves 71/ h e c are reversed. Then the valve 9 is turned to its opposite position, whereby air from the air-compressor is admitted into the tank F, and thereby the contents of said tank is forced through the pipe H. The tank F will at the same time be filled from the hopper E. The contents of each of the tanks before the compressed air is allowed to enter the same is a substantially homogeneous substance. If it is not entirely so, it becomes such in passing through the flexible pipe K to the shore. Each tank full is emptied into a separate receiving-tank in the factory, and therefore an analysis of the contents of each of these receiving-tanks determines what material must be added to the contents of that receivingtank to makethe proper cement mixture.

The boat A may be moved about from time to time as may be necessary, and suitable machinery may be provided for this purpose, although since it constitutes no part of the present invention such machinery is not shown.

The machinery on the boat may be driven by an electric motor W, the conductor-wires for which may be attached to and supported by the flexible pipe K.

Having described our invention, we claim- 1. In combination, a boat, and, supported upon it, dredging mechanism, a pug-mill into which the material raised by the dredge is delivered, two air-tight tanks, valved pipes through which the products of the pug-mill may be delivered into said tanks respectively, a compressed-air apparatus, and valved pipes connecting it with the two tanks respectively, valved discharge-pipes for said tanks, and a flexible pipe connected with said dischargepipes and extended therefrom to the shore,- substantially as and for the purpose specified.
